CORPORATION OF PENNSYLVANIA.

the metal roof sheets of which the roof cov ering is composed, and in improved means for securing the roof covering upon the root substructure or framing of, the car.

The object of my invention is to reduce} the number otdifierent parts required toform a complete roofcovering, and to 'se-i cure the roof covering to the roof substruc- ,ture in such manner that the sagging, rack- 'ing, and twisting of the car body in service shall not result in straining, tearing, or buckling the roof covering. i

: Another object of my invention is the removal of clipsor other fastening means for securing the roof coveringalong theeaves of the car to a place less exposed to injury,

and the elimination of bolt Holes through the fascia board and'car siding at the eaves through which water may finditsway into the car.

Further-objects of myinvention will appear in connection with the description of the embodiment thereof illustrated in the accompanying drawings, and the novel features of my invention will be more par- ,ticularly, pointed out in the appended claims. v 1

In the drawings I have illustrated my invention embodied in a metal roof for a box car having inf-00d side and end plates 11, 12 and side ar-d end sheathing 13, 14., but its use is not restricted to cars having wood bodies. Referring to the drawings, metal carlines '15, T-shaped in cross sect-ion, are arranged at spaced intervals lengthwise of the car to extend across the car from side plate to side plate, the ends of the carlines being turned down outside the side plate and securely bolted thereto. lurlins' 16 extending lengthwise of the car and arranged parallel to each other at spaced intervals crosswise'of the car are securely bolted to the forming with carlines and to the end plates, the carlines and side and end plates arigid framework for supporting the roof coverfing. Filler strips 17 are nailed upon the tops of the purlins to support the roof sheets. In the form of construction shown in the drawings, the .carlines are bent in arcs of circles and arranged with their base flanges 18 resting on the side plates and their middle flanges or webs 19 extending upwardly, in parallel vertical curves, and the purlins are secured to the under sides there of forming a rigid upwardly arched frame work. Roof sheets 20, formed of heavy gal vanized iron or other suitable material and having their side margins flanged up and rebent inwardly to form hooked flanges 21,

tend from eaves to caves of thecar, and with their ends 22 turned down into rabbets 23 in the fascia boards 24 secured on the outside of the side sheathing of the car-at the caves. The thickness of the filler strips 17 is less than the height of the vertical webs of a clamping washer for securing the are arranged upon. the filler strips 17 to exof the seam covers.

. the car is permitted. The width and depth of the rabbet- 23 in the fascia boards 24 are slightly greater than necessary to accommo' date the turned down ends 22 of the roof sheets, thereby permitting slight movement of the root sheets crosswise of the car.

Seam covers 25 of inverted channel shape and having lateral flanges 26 extending outwardly from the lower edge of each side wall, are arranged upon the roof sheets at the joints between adjacent sheets to cover their upstanding side flanges and the webs of the carlines. -The'space within the seam cover is slightly wider than the overall distance from the inside extremity of the upstanding flange of one sheet to the inside extremity of the upstanding flange ofthe adjacent sheet, so that the root sheets are allowed some sidewise motion before their flanges come in contact'with the inside of the seam cap. The side walls of the seam caps are flared toward the lower edges where they meet the lateral flanges 26, thus providing an enlargedspace 27 between theside flanges of the roof sheets and the side Walls This space curves as a gutterto conduct water and dirt along the margins ofthe roof sheets and ofl the eaves. The tops'of the seam covers extend over the tops of the inwardly and downwardly rebent margins of the root sheet flanges at a distance above them, thus leaving aconsiderable space over the inturned margins of the roof sheet side flanges within the seam covers. Any water which may splash into this space will run off the slightly downwardly inclined inturned margins of the roof sheet side flanges, and down the inside walls of' the seam covers and so Qfi the eaves of the car. The ends of the seam covers are bent down over the eaves of the car, the downturned' to close theends of -the channel spaces beneath the seam covers and prevent water from entering these spaces and finding its way insideof the car. In order to form the folded end as shown in Fig. 6 of the drawings, the lateral flanges 26 are notched or cut away at the end of the sheet metal strip or blank from which the seam cap is formed, as shown in Fig. .7 of the drawingsyand the narrow end portion of the blankisfirst flattened out and then folded up at the edges and bent down tight across the end of the channel, the dotted the lines of fold. the end portions are are crimped longitudinally.

At the same time that flattened out, they The crimped digging into end portions 28 serving lines in Fig. 7 indicating middle I=part of the lownturned end of the seam cap is bent in, forming an inwardlyprojecting lugi 30 which projects into the rabbet in the upper corner of the fascia between the doivnturned ends 22 of the roof sheetsl The lower edges of the ends 28 of the seam covers lie outside the' downturned corners of the adjacent roof sheets and limit the outward sliding movement "of the sheets at the eaves.

The seam covers are rigidly 'secured to the vertical webs 19 ofjthe carlines by, means of bolts 31 inserted in; T slots 32 fhrmed in the top edges of the tarline webs}. The bolts are held in position in the slots "by locking pieces 33' provided with perforations 39 shaped to embrace the shank of the bolt. The locking piece is slipped down over the bolt and seated on the top of thecarline web, being provided with ribs 34k on its under side to embrace the edge of the Web. The locking pieces33 also serve as qaddles for supporting the seam covers, and" are shaped on their upper sides to fit the in side of the latter. The seam covers are perforated to receive the bolts and are slipped down over the saddles and secured thereto by washers 37 and nuts 38 on the bolts. .The seam covers are formed with up-- turned flanges 35 and the washers shaped to fit the top of the seam cover and provided with recesses to receive gaskets 36 slipped over the bolts'and clamped in place on top of the seam cover' bolthole flanges,

surrounding the bolt holes," 37 have their under sides thus insuring that no water shall find its.

bolt holes. After the nuts way through the the ends of the bolts are are tightened up riveted over to secure ing loose. At the ridge of the car the washers 37 are omitted and wood running board saddles 4:0 are bolted down upon the tops of the seam covers, the bolt hole flanges v the wood and forming a water tight joint therewith. The running boards 41 may be secured to the running board saddles by nails or other convenient means. If it is desired to use metal running board saddles the ends thereof may be formed on the under side to receive the seam covers and gaskets in a manner similar to the washers 37 and fastened by nuts in the same way.
